Hi Engineers of Reddit, I am after a silicone solution that i can use to save a pair of head phones. I want to use the silicone to cover an small cut in a pair of headphone cables, the cable is soft and rubbery (flexible). I have no idea where to start.

The coating is an elastomer plastic dissolved in solvent (toluene & naphtha). After the solvents evaporate, the rubber coating solidifies and will have shrunken a little bit. It is very strong and flexible. I use it on wiring and cables all the time.
